The palm-size Xtreme Micro Copter is the smallest and lightest RC helicopter in the world. It charges directly from the controller for up to 12 minutes of flight on a single charge. It’s made of lightweight but durable polypropylene foam and features an auto-stability system for indoor flying. It comes ready to operate. The Xtreme Micro Copter has been a best seller for Michelle Deutschmann since she brought it into Kaleidoscope Toys in Falmouth, Mass., in November 2006.― Thunder Electronics is “special and different, and price points are really good,” Owner Susan Pruett of Kilmarnock Toy Store in Kilmarnock, Va., told TDmonthly in spring 2007.
